Volvo Trucks launches a unique gearbox for heavy vehicles
STOCKHOLM --(Business Wire)--
Volvo Trucks is now launching I-Shift Dual Clutch, the first
transmission on the market with a dual clutch system for heavy vehicles.
Thanks to power-shift gear changes without any interruption in power
delivery, torque is maintained and the truck does not lose any speed
during gear changes. For the driver, the result is more comfortable and
efficient progress on the road.
"In situations that require a lot of gear changes, for instance on hills
or roads with lots of curves and bends, I-Shift Dual Clutch brings an
entirely new dimension to truck driving. Here at Volvo Trucks we are
immensely proud to be able to offer this innovation to our customers,"
says Claes Nilsson, President Volvo Trucks.
I-Shift Dual Clutch is a transmission consisting of two input shafts and
a dual clutch. This means that two gears can be selected at the same
time. It is the clutch that determines which of the gears is currently
active. I-Shift Dual Clutch is based on I-Shift, but the front half of
the gearbox has been redesigned with entirely new components.
"When driving it feels like you have access to two gearboxes. When one
gear is selected in one gearbox, the next gear is already prepared in
the other. With dual clutches, gear changes take place without any
interruption in power delivery. As a result, engine torque is maintained
and driving comfort is significantly improved," says Astrid Drewsen,
product manager for drivelines at Volvo Trucks.
Available from autumn 2014
I-Shift Dual Clutch will be available from autumn 2014 on the Volvo FH.
Transmissions with dual clutches are already used in cars, but Volvo
Trucks is the first manufacturer in the world to offer a similar
solution for series-produced heavy vehicles.
"For trucks, this gearbox will truly make a major difference to
driveability. The heavier the transport and the tougher the operating
conditions, the more you will gain with I-Shift Dual Clutch. Power-shift
gear changes, where there is no interruption in power delivery, means it
is easier to keep up with traffic, especially on tricky stretches of
roads. The result is more relaxed and safe driving," says Astrid Drewsen.
More efficient driving and increased driver comfort
I-Shift Dual Clutch is particularly effective in long haul operations
and conditions that require a lot of gear changing, for instance on
hills or on roads with lots of twists and turns, or when driving through
cities with plenty of roundabouts and traffic lights. I-Shift Dual
Clutch also makes a big difference when transporting moving or liquid
cargoes, such as animal transports and tanker operations, since the
seamless gear changes prompt less movement in the cargo itself. Thanks
to I-Shift Dual Clutch power-shifting, there is less risk of getting
stuck on slippery or uneven roads, for instance when hauling timber in
Another major advantage with the new transmission is that it improves
"In addition to efficient driving, the smooth gear changes also mean
that the in-cab environment feels quieter," says Astrid Drewsen.
I-Shift Dual Clutch will be available on the Volvo FH with Euro 6 D13
engines and with 460, 500 and 540 horsepower.
Facts, I-Shift Dual Clutch
· I-Shift Dual Clutch can basically be described as two gearboxes linked
together. When one gearbox is active, the next gear is preselected in
the other gearbox. During gear changing, the first gearbox is
disconnected at the same instant as the second gearbox is connected, so
gear changes take place without any interruption in power delivery.
· I-Shift Dual Clutch is based on the I-Shift transmission. Despite its
many new components the new gearbox is just 12 cm longer than a regular
· I-Shift Dual Clutch changes gear without any disruption to power
delivery. When driving in conditions where it is more optimal for the
transmission to skip a few gears, the transmission changes gear just
like a regular I-Shift unit.
· I-Shift Dual Clutch can change gears without any interruption in power
delivery, with the exception of the range-change, which takes place when
shifting from 6th to 7th gear.
· Smooth, gentle gear changes cut wear on the driveline and the rest of
· Fuel consumption with I-Shift Dual Clutch is the same as with regular
· I-Shift Dual Clutch will be available on the new Volvo FH as an
alternative to I-Shift and manual transmission.
